Describe the bug
So as you know my machine has end-stops on X & Y and I have a probe which I sometimes use on Z, but most of the time I just jog the Z axis into position at hit the "Zero out work offsets" for the Z axis in CNC.js. This sends G10 L20 P1 Z0 to which µCNC returns "Unsupported command".

What is your hardware
Describe your hardware:
https://github.com/jimsynz/uCNC/tree/master/

What was the GCode running
G10 L20 P1 Z0

Additional context
So I had a look at the parser source and I see that L20 is not supported and only L2 is supported. A quick google says that they're synonyms and should both have the same behaviour. I was about to open a PR to add it when I thought I'd better test it and sent G10 L2 P1 Z0 and got back an ok however the WPos for the Z axis is still a non-zero value.

$10=0
ok
> ?
<Idle|WPos:0.000,0.000,50.000|FS:0.000,0>
ok
> $10=1
ok
> ?
<Idle|MPos:0.000,0.000,50.000|FS:0.000,0>
ok
> $10=0
ok

<Idle|WPos:0.000,0.000,50.000|FS:0.000,0>

error:20 (Unsupported command)
> G10 L2 P1 Z0
ok

<Idle|WPos:0.000,0.000,50.000|FS:0.000,0|WCO:0.000,0.000,0.000>
ok

I noticed the addition of WCO:0,0,0 in the status, however if I'm understanding the G10 command it should be setting the work position, not the offset? Is that not right?

Thanks!

Hello, I am from China, I am a cnc enthusiast, my job is a machining center master, cnc is a hobby, I used this firmware from https://github.com/robomechs/6-AXIS-USBCNC- GRBL, I saw your source code today. I downloaded the source code to the linux system, installed arm-none gcc, and used the make command to compile, but after downloading, I connected the computer through the ch340g serial port module and sent $$ without any response, and then I tried to uncomment them separately in the boardmap_bluepill.h file//Setup COM pins (must match selected COM port)
//#define RX_BIT 10
//#define TX_BIT 9
//#define RX_PORT A
//#define TX_PORT A

And //#define COM_PORT 1
//#define TX_BIT 9
//#define TX_PORT A
//#define RX_BIT 10
//#define RX_PORT A
There is no response after compiling and downloading. I don’t know much about C++ and microcontrollers. Can you send me a HEX file of F103C8T6 to [email protected], and tell me whether the communication method is serial or USB virtual serial

Hi,

I am new in this field and I think reached to my last question. I have connected two motors on my Y-axis. In marlin firmware (on MKS Gen L V 2.1 Board = Ramps Board in pinouts (may be)), when updated for dual axis on Y axis, the machine run smoothly. However, I could not get the Y-Axis running with both the motors (though one is running and one is not) on GRBL or uCNC. Can you please guide me in this aspect.

(Edit) My second Y motor is attached to E1.

Best regards,
